UNITED STATES PATENT OFFICEo FRANK ROSEBROOK, OFLMIRA, NEW YORK.

CHICKEN-BROODER.

JPECIE'ICATION forming part of Letters Patent No. 317,210, dated May 5, 1885.

Application filed August 1, 1884. (No model.)

To all whom, it may concern,.-

Be it' known that I, FRANK RosEERook, of Elmira, Ghemung county, New York, have invented a new and Improved Chicken-Brooder, of which the following is a Full, clear, and exact description.

The object of my invention is to provide anew and improved brooder for brooding and nursing chickens or other young fowls, especially such as have been hatched in au incubator.

The invention consists in the construction and arrangement of parts, as will be hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, in which Figure l is a longitudinal sectional view on line x x of Fig. 2. Fig. 2 is a vertical transverse section on line y y of Fig. l; and Fig. 3 is a side or front elevation of the device, omitting the case.

The box or casing A has a low front, B, and a high back or rear wall, C, and on the top edges of the walls an inclined sash, D,'is secured, which forms the top of the brooder. On the fioor of the brooder a long sheet-metal box, E, is held at or near the rear wall,which box is provided in its top with a series of apertures, F, or with longitudinal or transverse slots, and in the said box hot-water pipes G circulate. A layer of sand, I-I, is spread on the top of the box, and to prevent the sand from dropping through the slots or apertures.

in the box, apertured covers are provided for said apertures or slots. v

Above the box E a series of rods or bars, J, are held parallel with the box and quite close together, from which rods or bars flannel or like strips, K, are suspended, the lower edges of the strips being directly above the layer of sand on the top of the box E. A pipe, L, conducts fresh air into the brooder. The hotwater pipes G heat the air in the box E, and the'hot air passes through the apertures or slots F and up between the flannel strips K, by which it is held for a time and then circulates in the box. The sand on the top of the box E is also heated. rlhe chicks at all times try to nd the warmest place, and will jump on the box E. Their bellies and legs will be kept warm by the warm sand on the box, and their backs are kept warm by the flannel strips K. The said flannel strips rest quite closely against the backs of the chicks, and thus keep the chicks Vas warm as the hen could keep them. The chicks cannot come in contact with any heated parts apt to burn or otherwise injure them. The fresh air drawn into the box E bythe pipe L is heated, and then rises, thus Ventilating the brooder thoroughly and preventing any accumulation of foul air.

Having thus described my invention,I claim as new and desire to secure by Letters Patent- 1. In a brooder, the combination, with the casing A, of the box E, surrounding heatingpipes, and provided in its top with apertures, a pipe for conducting fresh air into the box, and strips of flannel or analogous fabric held above-the box, substantially as herein shown and described.

2. In a brooder, the combination, with the casing A, of the box E, surrounding heatingpipes, and provided with apertures in its top, the pipe L, for conducting fresh air into the box E, the bars or rods J, held above the box E, and the iiannel strips K, suspended from the said bars or rods, substantially as herein shown and'described.
